Structural, morphological and magnetic properties of Sn doped CoFe2O4 nanoparticles

In this report, sol–gel synthesized CoFe2−xSnxO4 (x = 0.00, 0.05, 0.10, 0.15, 0.20) nanoparticles (NPs) were prepared from metal chloride precursors. To identify the ferrite phase formation TGA/TDA analysis was performed. X-ray diffraction (XRD) analysis confirms the formation of face centered cubic spinel structure of the CoFe2O4 NPs. Octahedral shaped crystalline ferrite nanoparticles are confirmed from Scanning electron microscopy (SEM) study. The crystallite size estimated from XRD data is well agreed with particles size measured from transmission electron microscope (TEM) image. Fourier Transform Infrared (FTIR) spectroscopy result shows the octahedral and tetrahedral stretching vibrational bonds, respectively. EDX analysis suggests the successful substitution of Sn in the CoFe2−xSnxO4. The room temperature and at 50 K magnetization measurement shows the ferromagnetic behavior.…
